In the lower part of the flue, a union tee has been mounted with an
inspection cap.
A 90° bend should not be installed as the first initial piece as the ashes
would quickly obstruct the passage of smoke, causing problems for the
draught of the flue. (See Fig. 6).
This type of installation (se Fig. 10) does not require an insulated flue as
the smoke tube has been assembled partly inside the house and partly
inside an existing flue.
In the lower part of the flue a union tee has been installed with a peephole
cap.
A 90° bend should not be installed as the first piece, as the ash would
quickly block the passage of smoke, causing problems for the draught of
the flue (See Fig. 6).
Please note the use of 2 45° bends, to guarantee that the ash falls in the
union tee with a peephole.
This type of installation (see Fig. 5), does not require an insulated flue, as
all the whole pipe has been assembled outside the house.
A union tee has been mounted in the lower part of the flue with a peep-
hole. A 90° bend should not be installed as the first piece as the ashes
would quickly block the passage of smoke, causing problems for the
draught of the flue. (See Fig. 6).
